Description

Technical Field

[0001] The present application relates to the technical field of automation equipment, and in particular to a transfer device. Background Art

[0002] Pallets are used to hold materials. In some production scenarios, auxiliary materials needed in the processing flow are placed on pallets to facilitate the retrieval of materials during the processing flow. During this process, the pallets need to be circulated so that the retrieval can proceed smoothly.

[0003] In the related art, in order to realize the transfer of pallets, it is usually necessary to set up loading stations, material picking stations and unloading stations, etc. The transfer device will take up a large space, and the transfer process generally uses vacuum suction cups to adsorb and move, which poses a risk of the pallet falling off, and the transfer process is not stable and reliable enough.

[0004] Application Contents

[0005] The present application provides a transfer device to solve the technical problems that current transfer devices occupy a large space and are not stable enough.

[0006] A transfer device provided in the present application has a first direction and a second direction intersecting each other, and the transfer device includes: a workbench having a supporting surface, and the workbench is provided with a through opening extending from the supporting surface along the first direction; a transfer mechanism, arranged on the supporting surface, the transfer mechanism includes a transfer platform and a transfer drive member for driving the transfer platform to move along the second direction, and the transfer platform moves within the area defined by the through opening; and a loading and unloading mechanism and a fixing mechanism, which are arranged on both sides of the workbench along the first direction, and the loading and unloading mechanism is located below the fixing mechanism; wherein the loading and unloading mechanism includes a loading assembly and a unloading assembly sequentially arranged along the second direction, and the fixing mechanism includes a first fixing assembly and a second fixing assembly for picking up and fixing the pallet, and in the first direction, the first fixing assembly is arranged opposite to the loading assembly, and the second fixing assembly is arranged opposite to the unloading assembly; wherein the loading assembly is used to send the pallet through the through opening to the first fixing assembly, and the unloading assembly is used to remove the pallet from the second fixing assembly and send it out along the through opening.

[0007] To implement the above technical solution, the lower part of the first fixed component corresponds to the first station, and the lower part of the second fixed component corresponds to the second station. In the initial state, the pallet loaded with materials is placed on the loading component, and the transfer table is located on the second station. The working process is as follows: the loading component drives the pallet to move along the first direction toward the first fixed component until it is sent to the corresponding position, and the first fixed component temporarily fixes the pallet, and the transfer table moves to the lower part of the pallet along the second direction, and the first fixed component releases the pallet, and the pallet falls on the transfer table; the material picking structure in the process flow takes the material from the pallet; when the material is completely taken, the transfer drive drives the transfer table to move to the lower part of the second fixed component, and the second fixed component takes the empty pallet, and the transfer table withdraws from the lower part of the second fixed component, and the second fixed component releases the empty pallet, and the empty pallet falls onto the unloading component and is thus sent out along the first direction. In the scheme of the embodiment of the present application, since the transfer table itself can be moved, the transfer table can integrate the functions of loading, unloading and picking up materials, and only two loading and unloading stations need to be set up. At the loading station, the loading component and the first fixed component relative to each other in the first direction cooperate with each other to complete the placement of the pallet on the operating surface of the transfer table, and then the transfer table moves to the unloading station, and the unloading component and the second fixed component relative to each other in the first direction cooperate with each other to complete the unloading process of the empty pallet. Only two stations are needed as a whole, which effectively saves space occupancy; and in the embodiment of the present application, the transfer table is movable, and the movement of the pallet between the first station and the second station along the second direction is achieved by the movement of the transfer table, and there is no need to use a fixed mechanism to drive the movement as in traditional technology, thereby ensuring reliability.

[0008] As one of the optional embodiments of the present application, the transfer drive member has a transfer moving part that moves along the second direction, and the transfer mechanism also includes a transfer lifting member, which is arranged on the transfer moving part and is used to drive the transfer platform to reciprocate along the first direction.

[0009] To implement the above technical solution, the transfer mechanism can not only drive the transfer platform to move along the second direction, but also drive the transfer platform to rise and fall along the first direction through the transfer lifting member, thereby realizing position adjustment of the transfer platform in two directions, which is more convenient and flexible when cooperating with the fixing mechanism and the loading and unloading mechanism.

[0010] As one of the optional embodiments of the present application, the transfer mechanism also includes a stabilizing component, which is arranged on the transfer moving part, and the stabilizing component includes: a fixed plate, fixedly arranged at one end of the transfer platform in the second direction; a movable plate, movably arranged at the other end of the transfer platform in the second direction; a stabilizing cylinder, which is arranged on the transfer moving part; wherein the movable plate is arranged at the end of the piston rod of the stabilizing cylinder, and the stabilizing cylinder is used to drive the movable plate to move in the second direction to cooperate with the fixed plate to clamp and fix the pallet.

[0011] To implement the above technical solution, the transfer mechanism itself integrates a stabilizing component for fixing the pallet products. When the transfer platform drives the pallet to move, the stability of the pallet can be properly guaranteed to avoid risks such as material damage due to the shaking of the pallet. In addition, the setting of the movable plate and the fixed plate allows the stabilizing component to adapt to pallets of different sizes, thereby improving the applicability of the transfer device.

[0012] As one of the optional embodiments of the present application, the stabilizing assembly also includes: a stabilizing bracket, which is arranged on the piston rod of the stabilizing cylinder; a telescopic rod, which is telescopically arranged on the stabilizing bracket along the second direction; an elastic member, which is sleeved on the outside of the telescopic rod; wherein the movable plate is arranged at one end of the telescopic rod away from the stabilizing bracket.

[0013] By implementing the above technical solution, the movable plate can more gently fix the pallet under the action of the telescopic rod and the elastic member, avoiding deformation and other problems that may be caused by rigid extrusion of the pallet, so as to ensure the normal use of the pallet. Because in the production process, the pallet is usually designed to be stacked together in multiple layers. If the pallet is deformed, it will lead to poor stacking, or the pallet will be difficult to separate after being stacked, which is not conducive to the smooth processing of the subsequent process.

[0014] As one of the optional embodiments of the present application, a support frame is arranged on the supporting surface, and a first fixed component is arranged on the support frame, and the first fixed component includes: a main body plate; an adjustment plate, which is rotatably arranged at both ends of the main body plate in the second direction, and the rotation axis of the adjustment plate extends along the first direction, and an adjustment groove extending along the second direction is provided on the adjustment plate; a vacuum adsorption rod extends along the first direction, and the vacuum adsorption rod can be slidably arranged in the adjustment groove; wherein, the outer wall of the vacuum adsorption rod is threadedly connected with at least two nuts, and the nuts are arranged on both sides of the adjustment plate in the first direction.

[0015] In order to implement the above technical solution, a specific structure of a first fixed component is proposed, and the vacuum adsorption rod can be positioned around the rotation axis through an adjustment plate, and can be slidably adjusted through an adjustment groove, thereby allowing the vacuum adsorption rod to be spatially adjusted, and can better adapt to pallets of different types or sizes.

[0016] As one of the optional embodiments of the present application, the first fixing assembly also includes a first driving member, which is fixedly disposed on the support frame. The first driving member has a first moving portion that moves along a first direction, and the main body plate is disposed on the first moving portion.

[0017] To implement the above technical solution, the first driving member can drive the main plate to move along the first direction, thereby driving the vacuum adsorption rod to move along the first direction, and cooperate with the position adjustment of the vacuum adsorption rod on the adjustment plate and the main plate to achieve more spatial position adjustments of the vacuum adsorption rod. This allows the first fixing component to provide more operating space when taking or placing the tray, and has higher flexibility in use.

[0018] As one of the optional embodiments of the present application, it also includes a third direction, the first direction, the second direction and the third direction intersect each other, two support frames are provided and are arranged on both sides of the through opening in the third direction, and each support frame is provided with a first fixing component.

[0019] By implementing the above technical solution, the two first fixing components cooperate with each other to temporarily fix the product more stably and reliably, thereby improving the stability of the processing process.

[0020] As one of the optional embodiments of the present application, it also includes a third direction, the first direction, the second direction and the third direction intersect each other, a support frame is arranged on the supporting surface, and the transfer device also includes a separation mechanism, the separation mechanism is arranged on the support frame, the separation mechanism is used to separate the multi-layer pallets, the separation mechanism includes a separation cylinder arranged on the support frame and a separation paddle arranged at the end of the piston rod of the separation cylinder, the separation cylinder is used to drive the separation paddle to move along the third direction to insert the separation paddle into the gap between the two layers of pallets.

[0021] To implement the above technical solution, if multiple layers of stacked trays are loaded, after the first fixing component takes the top tray, the top tray may stick to the bottom tray. This is because there is attraction between adjacent trays due to deformation or vacuum adsorption force between the trays, which will cause the top tray to exert a greater drag force on the first fixing component, making it difficult to fix the top tray. The separation mechanism can separate the two trays more smoothly, thereby improving the smoothness of processing.

[0022] As one of the optional embodiments of the present application, it also includes a third direction, the first direction, the second direction and the third direction intersect each other, the transfer device also includes a support frame, two support frames are provided and are arranged on both sides of the opening in the third direction, the second fixed component includes: a left drive member and a right drive member, which are respectively arranged on the two support frames; a left support plate and a right support plate, which are respectively arranged on the left drive member and the right drive member; the left drive member and the right drive member are used to drive the left support plate and the right support plate to move closer to or away from each other.

[0023] As one of the optional embodiments of the present application, the loading assembly includes a loading drive member, which is arranged on a workbench, and the loading drive member has a loading movable part that moves back and forth along a first direction; a feeding plate, which is arranged on both sides of the loading movable part in a second direction; and a loading conveyor belt, which extends along a third direction for feeding materials to the feeding plate.

[0024] One of the above technical solutions has the following advantages or beneficial effects:

[0025] In the scheme of the embodiment of the present application, since the transfer table itself can be moved, the transfer table can integrate the functions of loading, unloading and picking up materials, and only two loading and unloading stations need to be set up. At the loading station, the loading component and the first fixed component relative to each other in the first direction cooperate with each other to complete the placement of the pallet on the operating surface of the transfer table, and then the transfer table moves to the unloading station, and the unloading component and the second fixed component relative to each other in the first direction cooperate with each other to complete the unloading process of the empty pallet. Only two stations are needed as a whole, which effectively saves space occupancy; and in the embodiment of the present application, the transfer table is movable, and the movement of the pallet between the first station and the second station along the second direction is achieved by the movement of the transfer table, and there is no need to use a fixed mechanism to drive the movement as in traditional technology, thereby ensuring reliability.

[0044] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the term "and / or" in this article is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0046] In the prior art, the transfer device for pallets generally includes a fixed workbench, and pallets containing materials are stacked on one side of the workbench. In the processing flow, the pallets containing materials are transported from the first area to the workbench, and then the material-retrieving mechanism retrieves the materials above the workbench, and the empty pallets after the material-retrieving is transported from the workbench to the other side of the workbench. Therefore, in the prior art, it is generally necessary to set up a loading station, a retrieving station, and a unloading station, etc. The transfer device will take up a large space, and the transfer process generally uses a vacuum suction cup to absorb and move, there is a risk of the pallet falling off, and the transfer process is not stable and reliable.

[0047] The following is combined with Figure 1-9 The present application is further described.

[0048] Reference Figure 1 , an embodiment of the present application provides a transfer device having an intersecting first direction Z, a second direction X and a third direction Y. In the present embodiment, the first direction Z refers to the direction of gravity. The transfer device includes a workbench 1, and the workbench 1 has a supporting surface 10. The workbench 1 is provided with a substantially rectangular opening 100 extending along the first direction Z from the supporting surface 10, and the length direction of the opening 100 is parallel to the second direction X. Specifically, the workbench 1 here refers to a flat plate-like structure, and the supporting surface 10 refers to the upper surface of the workbench 1 located in the first direction Z. In the embodiment of the present application, a basic frame 1a is arranged below the workbench 1, and the workbench 1 is fixedly arranged at the top of the basic frame 1a located in the first direction Z.

[0049] Reference Figure 1 , Figure 2 and Figure 3 The transfer device also includes a transfer mechanism 2, a loading and unloading mechanism 3 and a fixing mechanism 4 which are arranged based on the workbench 1 and the basic frame 1a.

[0050] Among them, the transfer mechanism 2 is arranged on the supporting surface 10, and the transfer mechanism 2 includes a transfer platform 21 and a transfer driving member 22 for driving the transfer platform 21 to move along the second direction X, and the transfer platform 21 moves within the defined area of ​​the passage 100. Specifically, the transfer driving member 22 is an electric cylinder module, and a transfer moving part 20 is fixedly connected to the moving plate of the electric cylinder module, and the transfer platform 21 is arranged on the transfer moving part 20. It can be understood that the movement of the transfer platform 21 within the defined area of ​​the passage 100 means that the range formed by the movement of the transfer platform 21 along the second direction X is within the defined area of ​​the passage 100. However, it should not be limited to that the transfer platform 21 can only move within this range.

[0051] It should be noted that in some optional embodiments, the transfer drive 22 can also be replaced by other structures. For example, the transfer drive 22 can be a combination of a cylinder and a linear slide rail, and the cylinder drives the transfer platform 21 to move on the linear slide rail. This structure of the transfer drive 22 has a lower cost, but its stability is relatively lower than that of the electric cylinder module.

[0052] The loading and unloading mechanism 3 and the fixing mechanism 4 are arranged on both sides of the workbench 1 along the first direction Z, and the loading and unloading mechanism 3 is located below the fixing mechanism 4. The loading and unloading mechanism 3 includes a loading assembly 31 and a unloading assembly 32 arranged in sequence along the second direction X, and the fixing mechanism 4 includes a first fixing assembly 41 and a second fixing assembly 42 for picking up and fixing the pallet. In the first direction Z, the first fixing assembly 41 is arranged opposite to the loading assembly 31, and the second fixing assembly 42 is arranged opposite to the unloading assembly 32; the loading assembly 31 is used to send the pallet through the through opening 100 to the first fixing assembly 41, and the unloading assembly 32 is used to remove the pallet from the second fixing assembly 42 and send it out along the through opening 100.

[0053] In the above, the lower part of the first fixed component 41 corresponds to the first station, and the lower part of the second fixed component 42 corresponds to the second station. In the initial state, the pallet loaded with materials is placed on the loading component 31, and the transfer platform 21 is located on the second station. The working process is as follows: the loading component 31 drives the pallet to move along the first direction Z toward the first fixed component 41, until it is sent to the corresponding position, the first fixed component 41 temporarily fixes the pallet, and the transfer platform 21 moves to the lower part of the pallet along the second direction X, the first fixed component 41 releases the pallet, and the pallet falls on the transfer platform 21; the material picking structure in the process flow takes the material from the pallet; when the material is completely taken, the transfer drive 22 drives the transfer platform 21 to move to the lower part of the second fixed component 42, the second fixed component 42 takes the empty pallet, the transfer platform 21 withdraws from the lower part of the second fixed component 42, the second fixed component 42 releases the empty pallet, and the empty pallet falls on the unloading component 32 and is thus sent out along the first direction Z. In the scheme of the embodiment of the present application, since the transfer platform 21 itself can be moved, the transfer platform 21 can integrate the functions of loading, unloading and picking up materials, and only two loading and unloading stations need to be set up. At the loading station, the loading component 31 and the first fixed component 41 relative to each other in the first direction Z cooperate with each other to complete the placement of the pallet on the operating surface of the transfer platform 21, and then the transfer platform 21 moves to the unloading station, and the unloading component 32 and the second fixed component 42 relative to each other in the first direction Z cooperate with each other to complete the unloading process of the empty pallet. Only two stations are needed as a whole, which effectively saves space occupancy; and in the embodiment of the present application, the transfer platform 21 is movable, and the movement of the pallet between the first station and the second station along the second direction X is achieved by the movement of the transfer platform 21, and there is no need to use the fixing mechanism 4 to drive the movement as in the traditional technology, thereby ensuring reliability.

[0054] The following is a detailed introduction to the transfer mechanism 2.

[0055] Reference Figure 3 and Figure 4 As one of the optional embodiments of the present application, the transfer driving member 22 has a transfer moving part 20 that moves along the second direction X, and the transfer mechanism 2 also includes a transfer lifting member 23, which is arranged on the transfer moving part 20, and the transfer lifting member 23 is used to drive the transfer platform 21 to reciprocate along the second direction X. Specifically, the transfer driving member 22 is an electric cylinder module, the transfer moving part 20 is bolted and fixed on the moving plate of the electric cylinder module, and the transfer platform 21 is arranged on the transfer moving part 20 so as to be driven to reciprocate along the second direction X.

[0056] As described above, the transfer mechanism 2 can not only drive the transfer platform 21 to move along the second direction X, but also drive the transfer platform 21 to rise and fall along the first direction Z through the transfer lifting member 23, thereby realizing the position adjustment of the transfer platform 21 in two directions, which is more convenient and flexible when cooperating with the fixing mechanism 4 and the loading and unloading mechanism 3.

[0057] Reference Figure 3 , Figure 4 and Figure 5 As one of the optional embodiments of the present application, the transfer mechanism 2 further includes a stabilizing component 24, which is disposed on the transfer moving part 20. The stabilizing component 24 is used to fix the pallet on the transfer platform 21 to ensure the stability of the pallet during movement.

[0058] Specifically, the stabilizing assembly 24 includes a fixed plate 241, a movable plate 242, a fixed bracket and a stabilizing cylinder 243, wherein the fixed plate 241 is fixedly disposed at one end of the transfer platform 21 in the second direction X; the movable plate 242 is movably disposed at the other end of the transfer platform 21 in the second direction X. The stabilizing cylinder 243 is fixedly disposed on the transfer moving part 20, the stabilizing bracket 244 is disposed on the piston rod of the stabilizing cylinder 243, and the movable plate 242 is disposed on the fixed bracket. The stabilizing cylinder 243 drives the stabilizing bracket 244 to move along the second direction X, thereby driving the movable plate 242 to move in the second direction X, so as to cooperate with the fixed plate 241 to clamp and fix the pallet.

[0059] To implement the above technical solution, the transfer mechanism 2 itself integrates a stabilizing component 24 for fixing the pallet product. When the transfer platform 21 drives the pallet to move, the stability of the pallet can be properly guaranteed to avoid risks such as material damage due to the shaking of the pallet. In addition, the setting of the movable plate 242 and the fixed plate 241 allows the stabilizing component 24 to adapt to pallets of different sizes, thereby improving the applicability of the transfer device.

[0060] Reference Figure 5 In one example, the stabilizing bracket 244 includes a connecting plate 2441 fixedly connected to the end of the piston rod of the stabilizing cylinder 243, an intermediate plate 2442 bolted to the top of the connecting plate 2441, and a connecting block 2443 fixedly arranged on the intermediate plate 2442. The connecting plate 2441 extends along the third direction Y. The stabilizing assembly 24 also includes a telescopic rod 245 and an elastic member 246. The telescopic rod 245 is telescopically arranged on the connecting block 2443 along the second direction X, and the elastic member 246 is sleeved on the outer side of the telescopic rod 245. The movable plate 242 is arranged at one end of the telescopic rod 245 away from the connecting block 2443. Specifically, one end of the telescopic rod 245 close to the connecting block 2443 passes through the connecting block 2443 and can move back and forth along the second direction X. The end of the telescopic rod 245 is threadedly connected to a limit end 2450, and the limit end 2450 is larger than the outer diameter of the telescopic rod 245, so that the telescopic rod 245 can stably telescope and slide in the connecting block 2443 without being separated from the connecting block 2443. The elastic member 246 is configured as a buffer spring, and the elastic member 246 is sleeved on the outer wall of the telescopic rod 245 located between the connecting block 2443 and the movable plate 242.

[0061] To implement the above technical solution, the movable plate 242 can more gently fix the pallet under the action of the telescopic rod 245 and the elastic member 246, avoiding deformation and other problems that may be caused by rigid extrusion of the pallet, so as to ensure the normal use of the pallet. Because in the production process, the pallet is usually designed to be stacked together in multiple layers, if the pallet is deformed, it will lead to poor stacking, or the pallet is difficult to separate after being stacked, which is not conducive to the smooth processing of the subsequent process.

[0062] The details of the first fixing component 41 are introduced below.

[0063] Reference Figure 1 , Figure 6 and Figure 7 As one of the optional embodiments of the present application, a support frame 5 is provided on the supporting surface 10, and a first fixing component 41 is provided on the support frame 5. Specifically, two support frames 5 are provided and are respectively provided on both sides of the through opening 100 in the third direction Y, and a first fixing component 41 is provided on each support frame 5.

[0064] Reference Figure 6 to Figure 7 The first fixing assembly 41 includes a main body plate 411, an adjustment plate 412 arranged on the main body plate 411, and a vacuum adsorption rod 413 arranged on the adjustment plate 412. The main body plate 411 is a long strip-shaped flat plate extending along the second direction X. Two adjustment plates 412 are provided and are respectively rotatably arranged at the two ends of the main body plate 411 in the second direction X. Specifically, the adjustment plate 412 is rotatably adjusted by the cooperation of nuts and studs and can be positioned at a certain position. For example, studs are fixedly arranged at both ends of the main body plate 411, and the studs are inserted in the adjustment groove 4121. The adjustment plate 412 is away from the main body plate 411, and the outer wall of the end of the stud away from the main body plate 411 is threaded with a nut. When adjustment is required, the nut is rotated to rotate the adjustment plate 412, and then the position of the adjustment plate 412 can be fixed by tightening the nut. The rotation axis of the adjustment plate 412 extends along the first direction Z, and the adjustment plate 412 is provided with an adjustment groove 4121 extending along the second direction X. The vacuum adsorption rod 413 extends along the first direction Z, and the vacuum adsorption rod 413 is slidably disposed in the adjustment slot 4121. The outer wall of the vacuum adsorption rod 413 is threadedly connected with at least two nuts, which are disposed on both sides of the adjustment plate 412 in the first direction Z.

[0065] To realize the above technical solution, a specific structure of the first fixing component 41 is proposed, and the vacuum adsorption rod 413 can be adjusted around the rotation axis through the adjustment plate 412, and can be adjusted by sliding the position through the adjustment groove 4121, thereby giving the vacuum adsorption rod 413 spatial position adjustment, and can better adapt to different types or sizes of pallets. The two first fixing components 41 cooperate with each other to more stably and reliably temporarily fix the product, thereby improving the stability of the processing process.

[0066] As one of the optional embodiments of the present application, the first fixed component 41 also includes a first driving member 414, which is fixedly arranged on the support frame 5, and has a first moving portion 4140 that moves along the first direction Z, and the main body plate 411 is arranged on the first moving portion 4140. The first driving member 414 can drive the main body plate 411 to move along the first direction Z, thereby driving the vacuum adsorption rod 413 to move along the first direction Z, and cooperating with the position adjustment of the vacuum adsorption rod 413 on the adjustment plate 412 and the main body plate 411, so as to achieve more positions of the vacuum adsorption rod 413 in space, which enables the first fixed component 41 to provide more operating space when taking or placing the tray, and has higher flexibility in use. In the embodiment of the present application, the first driving member 414 is set as a cylinder.

[0067] Reference Figure 7 As one of the optional embodiments of the present application, the transfer device also includes a separation mechanism 6, which is arranged on the support frame 5. The separation mechanism 6 is used to separate multiple layers of pallets. The separation mechanism 6 includes a separation cylinder 61 arranged on the support frame 5 and a separation paddle 62 arranged at the end of the piston rod of the separation cylinder 61. The separation cylinder 61 is used to drive the separation paddle 62 to move along the third direction Y to insert the separation paddle 62 into the gap between the two layers of pallets.

[0068] To implement the above technical solution, if multiple layers of stacked trays are loaded, after the first fixing component 41 takes the top tray, the top tray may stick to the bottom tray. This is because there is an attractive force between adjacent trays due to deformation or vacuum adsorption force between the trays, which will cause the top tray to exert a large drag force on the first fixing component 41, making it difficult to fix the top tray. The separation mechanism 6 can separate the two layers of trays more smoothly, thereby improving the smoothness of processing.

[0069] The relevant structure of the second fixing assembly 42 is introduced below.

[0070] Reference Figure 1 and Figure 8As one of the optional embodiments of the present application, two support frames 5 are provided and are respectively arranged on both sides of the through opening 100 in the third direction Y. The second fixing assembly 42 includes a left driving member 421 and a right driving member 422, which are respectively arranged on the two support frames 5; and a left supporting plate 423 and a right supporting plate 424, which are respectively arranged on the left driving member 421 and the right driving member 422; the left driving member 421 and the right driving member 422 are used to drive the left supporting plate 423 and the right supporting plate 424 to move closer to or away from each other. In order to facilitate the fixation of the pallet, the left supporting plate 423 and the right supporting plate 424 are both arranged in an L shape, so that the left supporting plate 423 and the right supporting plate 424 can simultaneously limit the pallet in the first direction Z and the third direction Y, so that the pallet can be more stable when the second fixing assembly 42 temporarily fixes the pallet.

[0071] The contents of the loading and unloading mechanism 3 are introduced in detail below.

[0072] Reference Figure 1 and Fig. 9 As one of the optional embodiments of the present application, the loading assembly 31 includes a loading drive 311, a feeding plate 312 and a loading conveyor belt 313, wherein the loading drive 311 is configured as an electric cylinder module, the loading drive 311 has a loading moving part 3110 that reciprocates along a first direction Z, and the loading moving part 3110 is fixedly disposed on a moving block of the electric cylinder module; two feeding plates 312 are provided and are disposed on both sides of the loading moving part 3110 in the second direction X; the loading conveyor belt 313 extends along a third direction Y for feeding materials to the feeding plate 312.

[0073] In one example, a baffle is provided at one end of the feeding plate 312 away from the feeding conveyor belt 313 to block the pallet sent from the feeding conveyor belt 313 to ensure the stability of transportation. Blocking plates 7 are also provided on both sides of the feeding conveyor belt 313 in the second direction X to limit the pallet to ensure the stability of the pallet movement.

[0074] As one of the optional embodiments of the present application, the unloading assembly 32 includes an unloading driving member 321, an unloading plate 322, and an unloading conveyor belt 323. The unloading driving member 321 is configured as an electric cylinder module, and the unloading driving member 321 has an unloading moving part 3210 that reciprocates along the first direction Z, and the unloading moving part 3210 is fixedly arranged on the moving block of the electric cylinder module; the unloading plate 322 is provided with two and is disposed on both sides of the unloading moving part 3210 in the second direction X; the unloading conveyor belt 323 extends along the third direction Y to be used for delivering the tray on the unloading plate 322.

[0075] It should be noted that, in some embodiments, the loading drive member 311 and the unloading drive member 321 can also be set to other structural forms. For example, optionally, the loading drive member 311 and the unloading drive member 321 both adopt a combination of a motor and a synchronous belt module, and the feed plate 312 is set on the synchronous belt. The motor drives the synchronous belt to rotate in a circle to drive the feed plate 312 to reciprocate along the first direction Z.

[0076] The overall workflow is as follows: the area corresponding to the bottom of the first fixing component 41 is called the first workstation, and the area corresponding to the bottom of the second fixing component 42 is called the second workstation. In the initial state, trays loaded with materials are stacked in multiple layers on the loading conveyor belt 313, and the transfer platform 21 is located on the second workstation.

[0077] The working process is as follows: start the loading conveyor belt 313 to transport the pallet to the feeding plate 312, start the loading drive 311 to drive the pallet to move along the first direction Z toward the first fixing component 41 until it is sent to the corresponding position, and the four vacuum adsorption rods 413 of the two first fixing components 41 absorb the four corners of the pallet to temporarily fix the pallet.

[0078] Start the separation cylinder 61 in the separation mechanism 6, drive the separation paddle 62 to insert into the gap between the two layers of pallets, assist in pallet separation, the loading drive 311 moves the remaining pallets downward, and the first drive 414 in the first fixed assembly 41 drives the topmost pallet to move upward, completing the layered separation process of the pallets.

[0079] The transfer drive 22 drives the transfer platform 21 to move below the pallet along the second direction X, and the first fixing assembly 41 releases the pallet, and the pallet falls on the transfer platform 21. Then, the stabilizing assembly 24 is used to stably fix the pallet on the transfer platform 21.

[0080] The material taking structure in the process flow then takes the material from the tray. It should be noted that the transfer platform 21 can be taken by the material taking structure at the first station, that is, below the first fixed component 41, or it can be moved to the second station, that is, below the second fixed component 42. The embodiment of the present application is explained by taking the material at the first station as an example.

[0081] After all the materials are taken, the transfer drive 22 drives the transfer platform 21 to move to the bottom of the second fixed assembly 42, activates the left drive 421 and the right drive 422 in the second fixed assembly 42, and fixes the pallet through the left support plate 423 and the right support plate 424, so that the second fixed assembly 42 can take the empty pallet. Subsequently, the transfer platform 21 is withdrawn from the bottom of the second fixed assembly 42, and the second fixed assembly 42 releases the empty pallet, and the empty pallet falls onto the unloading assembly 32 and is thus sent out along the first direction Z.

[0082] In the scheme of the embodiment of the present application, since the transfer platform 21 itself can be moved, the transfer platform 21 can integrate the functions of loading, unloading and picking up materials, and only two loading and unloading stations need to be set up. At the loading station, the loading component 31 and the first fixed component 41 relative to each other in the first direction Z cooperate with each other to complete the placement of the pallet on the operating surface of the transfer platform 21, and then the transfer platform 21 moves to the unloading station, and the unloading component 32 and the second fixed component 42 relative to each other in the first direction Z cooperate with each other to complete the unloading process of the empty pallet. Only two stations are needed as a whole, which effectively saves space occupancy; and in the embodiment of the present application, the transfer platform 21 is movable, and the movement of the pallet between the first station and the second station along the second direction X is achieved by the movement of the transfer platform 21, and there is no need to use the fixing mechanism 4 to drive the movement as in the traditional technology, thereby ensuring reliability.

[0083] The above description is only a partial implementation method of the embodiments of the present application and does not constitute any form of limitation on the application. The protection scope of the embodiments of the present application is not limited thereto. Any simple modifications, equivalent changes and modifications that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the embodiments of the present application should be covered within the protection scope of the embodiments of the present application.
